Abstract: (Elsevier)

If scale invariance is exact, unparticles are unlikely to be probed in colliders since there are stringent constraints from astrophysics and cosmology. However these constraints are inapplicable if scale invariance is broken at a scale μ≳1 GeV . The case 1 GeV≲μ

unparticle: vector
scaling: violation
coupling: (fermion unparticle)
astrophysics
electron positron: annihilation
muon: pair production
angular distribution: asymmetry
channel cross section
resonance: effect
Z0: width
